Lake Pepin, so called by the French, appears to be only an expansion of the Mississippi. It commences at the entrance of the Sauteaux, and bears N. 55° W. 12 miles to Point de Sable, which is a neck of land making out about one mile into the lake from the W. shore, and is the narrowest part of the lake. From here to the upper end the course is nearly due W. about 10 miles, making its whole length 22 miles, and from 4 to 1½ miles in width; the broadest part being in the bay below Point de Sable. This is a beautiful place; the contrast of the Mississippi full of islands, and the lake with not one in its whole extent, gives more force to the grandeur of the scene. The French, under the government of M. Frontenac, drove the Reynards or Ottaquamies [Outagamas, etc.] from the Ouiscousing, pursued them up the Mississippi, and, as a barrier, built a stockade [Fort Beauharnois?] on Lake Pepin on the W. shore, just below Point de Sable. As was generally the case with that nation, they blended the military and mercantile professions, by making their fort a factory for the Sioux. The lake, at the upper end, is three fathoms deep; but this, I am informed, is its shoalest part. From [Upper] Iowa river to the head of Lake Pepin, elk are the prevailing species of wild game, with some deer, and a few bear.

From the head of Lake Pepin for about 12 miles, to Cannon river, the Mississippi is branched out into many channels, and its bosom covered with numerous islands. There is a hill on the W. shore [at Red Wing], about six miles above the lake, called the Grange [la Grange, the Barn], from the summit of which you have one of the most delightful prospects in nature. When turning your face to the E. you have the river winding in three [South, Middle, and North] channels at your feet; on your right the extensive bosom of the lake, bounded by its chain of hills; in front, over the Mississippi, a wide extended prairie; on the left the valley of the Mississippi, open to view quite to the St. Croix; and partly in your rear, the valley through which passes Riviere au Canon. When I viewed it, on one of the islands below appeared the spotted lodges of Red Wing's band of Sioux. The white tents of the traders and my soldiers, and three flags of the United States waving on the water, gave a contrast to the still and lifeless wilderness around and increased the pleasure of the prospect.

From Cannon river to the St. Croix, the Mississippi evidently becomes narrower, and the navigation less obstructed by islands. St. Croix river joins the Mississippi on the E., and bears from the latter almost due N. It is only 80 yards wide at its mouth, but 500 yards up commences [Lower] Lake St. Croix, which is from 1½ to 3 miles wide, and 36 long. This river communicates with Lake Superior by the Burnt river, by a portage of half a mile only, and in its whole extent has not one fall or rapid worthy of notice.[VII-12] This, with the mildness of its current, and its other advantages, render it by far the most preferable communication which can be had with the N. W. from this part of our territories. Its upper waters are inhabited by the Fols Avoins and Sauteaux, who are supplied by the agents of the North West Company; and its lower division, by the Sioux and their traders.

The Mississippi from Cannon river is bounded on the E. by high ridges, but the left is low ground. The timber is generally ash and maple, except the cedar of the cliffs. From the St. Croix to the St. Peters the Mississippi is collected into a narrow compass; I crossed it at one place with 40 strokes of my oars,[VII-13] and the navigation is very good. The E. bank is generally bounded by the river ridges, but the W. sometimes by timbered bottom or prairie. The timber is generally maple, sugar-tree, and ash. About 20 miles below the entrance of the St. Peters, on the E. shore, at a place called the Grand Morais [Marais, Big Marsh, now Pig's Eye marsh or lake], is situated Petit Corbeau's village of 11 log houses. For a description of the St. Peters see the chart herewith.

From the St. Peters to the Falls of St. Anthony the river is contracted between high hills, and is one continual rapid or fall, the bottom being covered with rocks which in low water are some feet above the surface, leaving narrow channels between them. The rapidity of the current is likewise much augmented by the numerous small, rocky islands which obstruct the navigation. The shores have many large and beautiful springs issuing forth, which form small cascades as they tumble over the cliffs into the Mississippi. The timber is generally maple. This place we noted for the great quantity of wild fowl.

As I ascended the Mississippi, the Falls of St. Anthony did not strike me with that majestic appearance which I had been taught to expect from the descriptions of former travelers. On an actual survey I find the portage to be 260 poles; but when the river is not very low, boats ascending may be put in 31 poles below, at a large cedar tree; this would reduce it to 229 poles. The hill over which the portage is made is 69 feet in ascent, with an elevation at the point of debarkation of 45°. The fall of the water between the place of debarkation and reloading is 58 feet; the perpendicular fall of the shoot is 16½ feet. The width of the river above the shoot is 627 yards; below, 209. For the form of the shoot, see a rough draught herewith.[VII-14] In high water the appearance is much more sublime, as the great quantity of water then forms a spray, which in clear weather reflects from some positions the colors of the rainbow, and when the sky is overcast covers the falls in gloom and chaotic majesty.

From the Falls of St. Anthony to Rum river, the Mississippi is almost one continual chain of rapids, with the eddies formed by winding channels. Both sides are prairie, with scarcely any timber but small groves of scrub oak. Rum river is about 50 yards wide at its mouth, and takes its source in Le Mille Lac,[VII-15] which is but 35 miles S. of Lower Red Cedar Lake. The small Indian canoes ascend this river quite to the lake, which is considered as one of the best fur hunting-grounds for some hundreds of miles, and has been long a scene of rencounters between the hunting-parties of the Sioux and Sauteaux. Last winter a number of Fols Avoins and Sioux, and some Sauteaux wintered in that quarter. From Rum river to Leaf river, called [not] by Father Hennipin and [but by] Carver the river St. Francis,[VII-16] and which was the extent of their travels, the prairies continue with few interruptions. The timber is scrub-oak, with now and then a lonely pine. Previous to your arrival at Leaf river, you pass Crow [Carver's Goose] river on the W., about 30 yards wide, which bears from the Mississippi S. W. Leaf river is only a small stream of not more than 15 yards over, and bears N. by W.

The elk begin to be very plenty; there are also some buffalo, quantities of deer, raccoons, and on the prairie a few of the animals called by the French brelaws [blaireaux, badgers].

Thence to Sac [or Sauk] river, a little above the Grand Rapids [Sauk Rapids, St. Cloud, etc.], both sides of the river are generally prairie, with skirts of scrub-oak. The navigation is still obstructed with ripples, but with some intermissions of a few miles.

At the Grand Rapids the river expands to about ¾ of a mile in width, its general width not being more than ⅗ of a mile, and tumbles over an unequal bed of rocks for about two miles, through which there cannot be said to be any channel; for, notwithstanding the rapidity of the current, one of my invalids who was on the W. shore waded to the E., where we were encamped. The E. bank of these rapids is a very high prairie; the W. scrubby wood-land. The Sac river is a considerable stream, which comes in on the W. and bears about S. W., and is 200 yards wide at its mouth.
